This is a large refactor that aims to improve performance by offloading RelayPool computations into a separate actor outside the main thread. This should reduce congestion on the main thread and thus improve UI performance. Also, the internal subscription callback mechanism was changed to use AsyncStreams to prevent race conditions newly found in that area of the code. Changelog-Fixed: Added performance improvements to timeline scrolling Signed-off-by: Daniel D’Aquino <daniel@daquino.me>
